Abstract：
UNASSIGNED: The aim of this study is to report the outcome of balloon catheter dilation as the primary treatment of congenital nasolacrimal duct obstruction in children of all ages.
UNASSIGNED: A 10-year retrospective study of 148 children (270 eyes), aged 9 to 159 months (mean age: 29.6 ± 17.7 months), who previously had not undergone a nasolacrimal surgical procedure and who presented with clinical signs of nasolacrimal duct obstruction, was conducted. All children underwent balloon catheter dilation of the nasolacrimal duct.
UNASSIGNED: Treatment success, defined as complete resolution of nasolacrimal duct obstruction symptoms present at follow-up visits at 1 week and up to 6 months after surgery, was 87% (234 of 270 eyes). Partial success was defined as occasional tearing which was acceptable to parents and present in 3% (nine eyes). Only 10% of the children underwent a second procedure due to complete failure. In a sub-analysis by age groups-under 18 months, between 18 and 36 months, and above 36 months-complete resolution rates were 85%, 93%, and 77%, and partial success rates were 3%, 3%, and 4%, respectively. There was a statistically significant difference between the age groups (p = .007).
UNASSIGNED: In this large cohort of patients with nasolacrimal duct obstruction, balloon catheter dilation was successful as a primary treatment for congenital nasolacrimal duct obstruction, particularly under the age of 36 months.

摘要：
■这项研究的目的是报告球囊导管扩张作为所有年龄段儿童先天性鼻泪管阻塞的主要治疗方法的结果。
■一项针对148名儿童（270眼）的10年回顾性研究，9至159个月（平均年龄：29.6±17.7个月），以前没有经历过鼻泪管外科手术，并且出现鼻泪管阻塞的临床症状，进行了。所有儿童均接受鼻泪管球囊导管扩张术。
■治疗成功，定义为手术后1周至6个月随访时出现的鼻泪管阻塞症状完全缓解，87％（270只眼睛中的234只）。部分成功被定义为偶尔流泪，父母可以接受，并且有3％（九只眼睛）。由于完全失败，只有10％的儿童接受了第二次手术。在按年龄分组的亚分析中，18个月以下，在18到36个月之间，36个月以上的分辨率为85%，93%,77%,部分成功率为3%，3%,4%,分别。各年龄组之间存在统计学上的显著差异(p=.007)。
■在这一庞大的鼻泪管阻塞患者队列中，球囊导管扩张术作为先天性鼻泪管阻塞的主要治疗方法是成功的，尤其是36个月以下。
